Types of casting and insulating powder used in the Iran’s steel industry
Continuous casting mold powder with the commercial code Rinox is used in billeting and slab production of simple carbon steels and low-alloy steels. Quality of the product has been improved by having sufficient lubricant in the melt which facilitate the passage of melt by removing friction between the mold wall and billet.
Moreover, this product creates appropriate viscosity and controls the heat transfer between the mold and the melt and eases the absorption of harmful melting impurities and protects the melt from oxidation.
This product with commercial code TD Duropol is an insulation powder with acid properties that is used in ladle and tundish to keep the melt warm. Besides high insulating properties, this product is very light-weight. Low density of about 0.7 g/cm3, excellent insulating properties, fluidity and smooth and fast flow on melting, the minimum amount of slag, as well as the lack of smoke and dust emission are among the product’s properties. Also, this product keeps the ladle clean after casting and increases the longevity of refractories and reduces non-metallic impurities.
This product with the commercial code Duropol AP is used to keep the feeding surface of steel, cast iron, copper and nickel-based alloys warm with high insulating power, low smoke and low density. Moreover, its low carbon-content improves the melt quality. Duropol AP eliminates the considerable heat losses caused by the lack of feeder cover, and the average sensitivity of this product makes it suitable for a wide range of feeder above 120 mm in diameters.
This product is supplied in 20 kg double-wall bags.
This product with commercial PW1 is due to its exothermic and isothermic properties causes raising and stabilizing the temperature which results in increasing the feeding efficiency and creating a thermal gradient between the part and the feeding, and then directional freezing occurs. PW1 mixture is molded into a sleeve and any required shape.
